The sum of the lengths of the two sides of an isosceles triangle is 65cm, and its perimeter is 100cm. Calculate the lengths of the sides of this triangle.
The perimeter is the sum of the lengths of all sides. The triangle is isosceles, which means that the two sides are equal. The sum of these two sides is 65 cm. So, to find these 2 sides, you need to divide this sum by 2. One side is equal to 65/2 = 32.5 cm. To find the base, you need to subtract the sum of the lengths of the two sides of this isosceles triangle from this perimeter.
Base length = perimeter – the sum of the lengths of the sides of an isosceles triangle = 100 cm – 65 cm = 35 cm.
Answer: 2 equal sides of an isosceles triangle are equal to 32.5 cm, the base is 35 cm.
